The Virtual Bookcase Reviews of 'The Internet Security Guidebook: From Planning to Deployment':
Reviewer Rob Slade wrote:
The introduction outlines some of the basic types of attacks that can
happen over the Internet, and seems to concentrate on attacks against
machines, rather than people or companies. This emphasis on the
technical is odd, since the material provides very few technical
details, but does contain more than a little error and confusion. The
text of the book doesn't mention a specific target audience, although
the jacket notes seem to promote the work to CEOs and other senior
executives. Which is odd: the writing level seems more appropriate to
the home user.
Chapter one is an overview of security planning. Most of the
important parts of preparation are included, but the chapter structure
and even the figures are very confusing. There are many gaps in the
discussion of security reviews, and a number of odd and apparently
misplaced items have been inserted. Encryption is covered
simplistically, and the lack of depth in the material becomes a
problem in the chapter on network security. After twelve pages that
*don't* explain the Internet and OSI (Open Systems Interconnection)
models of networking, the text attempts to deal with a number of
Internet security tools, most of which rely on encryption and key
exchange. There are frequent errors and the sections sometimes even
provide contradictory and nonsensical explanations, such as the
statement that "unencoded" means both "not encrypted" and "not as
plain text." The basic outline of firewalls is better than is
provided in most general guides, although the description of circuit-
level gateways keeps referring to "stateful inspection" without ever
explaining what that is. The long evaluation section is,
unfortunately, the usual for this type of book: it does provide most
of the right questions to ask, but doesn't give the novice reader much
help in analyzing the answers. Authentication is a very important
topic in security, and it is too bad that the material on this subject
is so confused, and confusing. I find it very difficult to reconcile
the statement that there are "very few examples" of biometrics with
the existence of a great many fingerprint, palm geometry, iris,
voiceprint, and even face readers. The depiction of Kerberos is wrong
in some basic aspects, does not address the fundamental problems with
the Microsoft version, and does not relate in any way to the very
closely associated topic of single sign-on that immediately follows.
The discussion of PKI (Public Key Infrastructure) does do well in
covering the "build or buy" debate for a certificate authority.
Directory issues are not handled particularly well, and there are
other errors. (Excuse me? The Internet didn't exist before the mid-
1980s?) The chapter on messaging security is a real grab bag of
topics, none of which, with the possible exception of acceptable use,
are covered in sufficient depth. (Viruses and trojans get lumped into
this chapter, and the commentary is quite sloppy.) The basic outline
of risk analysis, including threat, impact, and probability, is good,
but the supporting material is not quite standard, and probably not
very helpful to the target audience. The chapter also fails to point
out the full scope of such an appraisal, as well as the importance of
looking at the aggregate risk. On the other hand, the review of
policy and procedures hardly seems to address policy creation at all.
This is another miscellaneous compendium of vulnerabilities, diving
into specifics and missing the bigger picture. The material on
incident response is generic, but does point out the foundational
concepts. There is little detail, and the text does concentrate on
dealing with events by severity, rather than by type. The book closes
off with an ordinary presentation on project planning.
I would be the first to admit that security can be a dry topic, and a
little humour can help to spice up the text. However, I am willing to
make an exception in the case of this book. The jokes added to the
text do nothing to improve it. They are intrusive, distracting, and
do not, in any way, help the reader to understand the topics under
discussion. Indeed, the attempts at comedy generally sidetrack the
reader from the central issues of the work, and simply confuse any
issue under discussion.
If this text is aimed at executive management, it definitely needs to
be tightened up and reorganized to eliminate duplicated material and
ensure the structure and arguments are easier to follow. Many points
raised throughout the work are important, but a number of vital issues
are not addressed, and the patchwork of writing level and quality of
information probably means that this is unsuitable as an only
introduction to security. The Internet, in fact, is not really a
major concern in this book, although it does get mentioned from time
to time. I would have difficulty in suggesting a group that would
benefit from this book, although it might serve as an adjunct text to
the security planning process, if ideas were being culled from
multiple sources.
